HP MSA 1040 Cable Configuration Guide (762786-001, March 2014)

3 Connecting the HP MSA 1040 array to expansion drive
enclosures
To connect the HP MSA 1040 array to expansion drive enclosures, connect a Mini-SAS to Mini-SAS
cable from the SAS expansion port on each HP MSA 1040 controller to an I/O module in the
drive enclosure. Cabling varies, depending on which of the two supported cabling schemes you
use:
• Fault-tolerant cabling
• Straight-through cabling
For more information about these cabling schemes, see “Fault-tolerant and straight-through
cabling” (page 8)
For more information about your HP MSA 1040, see the HP MSA 1040 Best Practices guide,
available on the HP website (http://www.hp.com/support/msa1040/BestPractices).

Drive enclosure connection guidelines
• Expansion drive enclosures can be hot-added to an HP MSA 1040 that is operating.
• Mini-SAS to Mini-SAS 0.5 m (1.64 ft) cables are provided with HP MSA 2040, P2000, and
D2700 drive enclosures (one for each I/O module).
• The maximum length cable supported for connecting drive enclosures is 2 m (6.56 ft).
• Use only supported cables. Cables longer than those supplied with the drive enclosure must
be purchased separately. For a list of cables available from HP, see the HP MSA 1040
QuickSpecs.
• The maximum number of enclosures supported in an HP MSA 1040 solution is four (one MSA
1040 array enclosure and up to three expansion drive enclosures).
